2. SAFETY INSTRUCTIONS
A. Keep this instruction booklet where it can always be easily consulted by
the operator or by maintenance personnel.
B. Before making an intervention or connection of any kind, make sure that
the mains are disconnected both from the instrument and from any device connected to it.
C. Warning: hot components may be inside the plastic housing of the
controller.
D. No user-serviceable parts are inside the plastic housing of the controller. E. The controller and any device connected to it must be installed in
compliance with the safety regulations in force. If these regulations are not complied with during installation, and if our product is not installed in compliance with the indications given in this instruction booklet, then this may result in the safety of the controller being comprimised. In particular, the ambient operating conditions for the controller given in our technical data must be complied with. Absolutely avoid: water condensation or excessive humidity, exposure to steam, corrosive or toxic gases, contact with any type of liquid, and exposure to shocks or extreme vibrations. Not complying with the above indications could cause malfunctions and entail unpredictable consequences.
F. This controller is guaranteed by Honeywell to have a specific immunity
level, in compliance with CE regulations, against irradiated and conducted electromagnetic disturbances. By irradiated electromagnetic disturbances we recommend to screen the controller with a metal screen connected to ground. To eliminate, or at least reduce conducted disturbances, which not only could propagate through the mains but also through the probes or the connected loads, carry out the electrical wiring according to the indications given in this instruction booklet. If necessary, use filters with suitable characteristics for specific applications and for the detected type of disturbance.
G. If the type of probe to be used will directly touch foodstuffs, make sure
that it is in compliance with the local sanitary and health regulations.
H. The controller has no type of protection for the connected loads, so
these must be protected against short circuits, over-current or over­voltage, excessive temperature, etc., by suitable protective means (such as fuses, suitable thermo-magnetic circuit breakers, thermal protections, etc.). At any rate, the electrical power lines that supply both the controller and any other device connected to it, either directly or through a transformer, must be manufactured in compliance with the regulations in force.
I. When the controller is used in appliances where any malfunction of said
controller could cause a form of risk to persons, animals or objects, it is ABSOLUTELY MANDATORY to provide a suitable protective/safety device, in addition to the controller, which independently starts to operate in case of a failure.
J. The controller cannot be used as critical component in life-support
devices or systems without a written approval expressly issued by the legal representative of Honeywell.
CAUTION
Disconnect the power supply before you begin installing the Icon controller. Do not reconnect the power supply until you have completed installation.

3. GENERAL DESCRIPTION
The Honeywell Icon 300 Series is a microprocessor controlled thermostat, powered by AC 230 V, 50/60 Hz, and operates with up to three NTC or PT1000 probes (air-on, air-off and evaporator probes), and has up to six relay outputs (alarm, auxiliary, light, compressor, defrost and fan), and two digital inputs (doorswitch and auxiliary). Icon 300 series has a RS485 serial line connection to enable the controller to interface to Honeywell Genus® network.
The Icon 300 series comes in two variants: Icon 343 (Part Number: ICON-343C) Icon 363 (Part Number: ICON-363C)
The Icon 300 series can be applied both in cooling and refrigeration applications and has the following features:
• satisfy the most diverse plant requirements for cooling/refrigeration with its
42 configurable parameters, that can be set very easily and quickly through the instrument keyboard.
• display the conditioned ambient temperature as well as the alarm messages
that refer to faulty cooling/refrigeration plant functions.
• control the conditioned ambient temperature through weighted average of
the air-on / air-off probes in order to maintain it under a set limit value (main set point + differential), by activating the compressor to lower said temperature every time it exceeds the main set point + differential value.
• control the defrost cycles of the cooling/refrigeration plant manually, through
the network or through the programmed mode; in the latter mode it is possible to set the starting times of up to six daily defrost cycles.
• control the defrost cycle time as well as the successive startup of the
cooling/refrigeration plant fan through the evaporator probe.
• select the Low Humidity mode (with a specific key) which keeps the fan of
4. OPERATOR MODES
The ICON 343C / 363C controller has three operating modes: A. Stand-by: The controller is not active and OFF is displayed. B. Programming: In this mode it is possible to set the configurable
parameter values of the thermostat.
C. Normal: In this mode the conditioned ambient temperature is displayed
and the digital outputs, the defrost cycles, and any case / coldroom alarms are monitored.

6. INSTALLATION
6.1. First Things
The controller must be installed in a place where it is protected from extreme vibration, impact, water, corrosive gases, steam, etc., and where temperature and humidity do not exceed the values given in the technical data sheet.
6.2. Probes
We recommend the use of probes such as Honeywell 2k ohm NTC thermistor temperature probes (Part Number: TP002K).
Both the air-on and air-off probe is to be installed inside the coldroom or refrigerated display case where it is protected from direct air flow (i.e., far from fans or doors) so that the average ambient temperature can be measured.
The evaporator probe must be installed in the coldest area between the evaporator fins, i.e., where the greatest amount of ice will form and far from the resistances or the area that warms up first during defrosting, in order to avoid anticipating termination of said defrost cycle.
6.3. Electrical Wiring
The wiring diagram of the ICON 343C / 363C controller is shown in Figs.1. & 2. We recommend the protection of the controllers power supply from
electromagnetic disturbances, voltage peaks, etc., especially applications in particularly critical industrial environments.
This can be done while carrying out the electrical wiring by keeping the following points in mind:
A. Keep the power output cable s for the compressor, motors, etc. separate
from those for the control part;
B. Keep the probe cables, the controller power cables and the attached load
power supply cables separate and far enough from each other, so they do not cross or form spirals;
C. Use mains filters to reduce disturbances at the controller power supply, as
well as filters for the loads in order to attenuate disturbances at the controller relay outputs;
D. If strong radio disturbances are present, screen the entire device with a
metal screen and connect it to ground.
E. Use correct wire gauges to avoid damaging the screw connectors.

WARNING
Disconnect the power supply before you begin installing the Icon controller. Do not reconnect the power supply until you have completed installation.
Please be aware that the relay outputs are live when controller is powered up.
The contacts are NOT volt free. Disconnect the power supply before you
begin any maintenance on the Icon controller.
EN2B-0004UK07 R0304 9
6.5. Probe Self Detect
The Icon 300 series has a feature that allows only the AIR-OFF probe to be fitted. If this function is used then the controller will not alarm on any probes that are missing.
Again, this applies to the AIR OFF probe if this is the only probe that is fitted, and therefore the weighting parameter pair must be set to 0%.
This function only applies from initial power up of the controller. If both the AIR -ON and AIR-OFF probes are fitted and the AIR-ON probe becomes faulty, then the controller will continue to function using the AIR-OFF probe, and the power to the controller would have to be cycled off and then on again.
